If you plan to distribute your game on Steam, VAC is a mandatory, free component. It scans running processes and memory for known cheat signatures, providing a baseline level of security for multiplayer matches on Steam servers.
An open-source initiative aimed at creating a modular, transparent anti-cheat system. It allows indie developers to customize detection methods and is ideal for those who prefer full control over their security infrastructure.
A suite of server-side tools for Counter-Strike: Global Offensive and Source engine games. It provides customizable detection for aimbots, wallhacks, and other modifications, serving as a cost-effective solution for Source-based indie projects.
While primarily a PHP encoder, it has utilities for securing game server scripts and config files. It helps prevent reverse engineering of server-side logic, which is crucial for maintaining integrity in web-based or hybrid game architectures.
Denuvo offers specific packages for smaller studios to protect executable integrity. While costly for AAA titles, their entry-level solutions provide strong protection against tampering and debugging for indie developers on PC platforms.
A Korean-developed anti-cheat that gained popularity for its aggressive detection methods. It offers a free developer program for smaller titles and is known for catching a wide variety of memory-editing cheats in real-time.
One of the older but still active anti-cheat solutions. It provides a free license for indie developers and focuses on protecting against client-side modifications and macro usage in both PC and web-based game environments.
A conceptual framework for building custom kernel-level protections. Open-source components exist that help indie developers understand and implement low-level hooking and process inspection techniques for unique security needs.
The Steamworks API provides basic utilities for verifying game integrity and reporting cheaters to Valve. Developers can leverage these built-in tools to create a custom anti-cheat layer that integrates directly with the Steam platform.
Ubisoft's proprietary anti-cheat solution is sometimes made accessible for partner indie titles or specific engine templates. It offers strong protection against multiplayer cheating and is deeply integrated with the Uplay ecosystem.
One of the earliest anti-cheat systems, still maintained for legacy projects. It is free for developers using supported game engines and is effective against older cheat methods, making it suitable for retro-style or classic multiplayer games.
Used for augmented reality games, this system detects GPS spoofing and location manipulation. Indie developers creating location-based games can adopt similar strategies or tools to ensure fair play and prevent location cheating.
Various GitHub repositories offer basic Python or C++ scripts for detecting common cheat signatures. These are not full solutions but serve as excellent starting points for indie developers to build custom, lightweight detection logic.
Epic’s development suite includes security features and anti-cheat integration options for Unreal Engine users. Indie devs using Unreal can leverage EOS for secure matchmaking and basic integrity checks without additional third-party costs.
Unity provides early access or beta packages for anti-cheat solutions integrated directly into the engine. These tools help developers implement server-authoritative checks and client-side validation to prevent common manipulation techniques.
While primarily a modding platform, Modio includes security features to prevent malicious mod injection. Indie developers can use its framework to secure user-generated content, indirectly protecting against mods that act as cheats.
